Abstract

Abstract Based upon the principle that the continual and prolonged downward pull by the neck muscles, facial muscles and facial skin upon the scalp constricts the scalp blood vessels which nourish the hair roots, this hollow pillow in response to the weight of the user''s head sets up a counter-acting upward force which counteracts the downward pull of the facial skin and consequently reduces the constriction of these blood vessels which feed the scalp and hence nourish the hair roots therein. To this end, the pillow is made of resilient foam plastic material with laterallyextending parallel air chambers separated from one another by laterally-disposed upwardly and rearwardly-inclined yielding partition walls. The weight of the user''s head produces a downward force which causes the slanting front and rear walls and partition walls to be tilted downwardly and rearwardly thereby producing an upwardly and rearwardly-inclined force which includes a horizontal component acting toward the top of the head and thereby counteracting the pull of the neck muscles, facial muscles and facial skin toward the chin of the user.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 111 words
A scalp relaxation pillow for reducing the tension of the scalp and consequently reducing the constriction of the blood vessels supplying blood to the hair roots in the scalp, said pillow comprising a hollow body of elastic deformable material having a top wall and a bottom wall disposed in a vertically-spaced relationship, a plurality of side walls extending between said top wall and said bottom wall and defining therewith a chamber, and horizontally-spaced approximately-parallel yieldable struts extending between said top wall and said bottom wall, all of said struts inclined relatively thereto in substantially the same direction toward one of said side walls and subdividing said chamber into horizontally-spaced approximately-parallel subchambers.
Claim 2
Dependent Claim 111 words
A scalp relaxation pillow for reducing the tension of the scalp and consequently reducing the constriction of the blood vessels supplying blood to the hair roots in the scalp, said pillow comprising a hollow body of elastic deformable material having a top wall and a bottom wall disposed in a vertically-spaced relationship, a plurality of side walls extending between said top wall and said bottom wall and defining therewith a chamber, and horizontally-spaced approximately-parallel yieldable struts extending between said top wall and said bottom wall, all of said struts inclined relatively thereto in substantially the same direction toward one of said side walls and subdividing said chamber into horizontally-spaced approximately-parallel subchambers.
Claim 3
Dependent Claim 29 words
A scalp relaxation pillow, according to claim 1, wherein said body has a central portion and also has opposite end portions tapered laterally outward away from said central portion.
Claim 4
Dependent Claim 17 words
A scalp relaxation pillow, according to claim 1, wherein said struts include a plurality of partition walls.
Claim 5
Dependent Claim 44 words
A scalp relaxation pillow, according to claim 1, wherein said side walls include approximately parallel forward and rearward walls, and wherein said forward and rearward walls are also inclined relatively to said top and bottom walls in approximately the same direction as said struts.
Claim 6
Dependent Claim 34 words
A scalp relaxation pillow, according to claim 3, wherein said struts include a plurality of said inclined partition walls having central portions and opposite end portions also tapered laterally away from said central portions.
Claim 7
Dependent Claim 66 words
A scalp relaxation pillow, according to claim 1, wherein a hollow body superstructure is superimposed upon said body and has an uppermost wall and a superstructure chamber disposed between said uppermost wall and said top wall, and also has horizontally-spaced approximately-parallel yieldable auxiliary struts so inclined and extending between said uppermost wall and said top wall and subdividing said superstructure chamber into horizontally-spaced approximately-parallel auxiliary sub-chambers.
Claim 8
Dependent Claim 22 words
A scalp relaxation pillow, according to claim 6, wherein said superstructure extends only part way over said top wall of said body.
